基于漁業(yè)統(tǒng)計數(shù)據(jù)的南海區(qū)漁業(yè)資源可捕量評估
[Abstract]:Scientific determination of the allowable catch of marine fishery is the premise and key to carry out the management of fishing quota. There are many kinds of fishery resources in Nanhai area, there are no obvious economic fish species, and the output statistics are not perfect, which makes the quantitative evaluation of the available catch more difficult. Based on the statistical data of fishery yield, a simplified yield model was used to evaluate the total fishery resources and 11 important economic groups in the South China Sea area. The results showed that the maximum sustainable yield of fishery resources in Nanhai area was 3.086 million t and the total allowable catch was 2.469 million ~ 2.778 million t. According to the evaluation results of 11 important economic groups, these groups have been overfished to varying degrees since the 1990s. At present, there are 6 groups with higher recovery ability, such as Cymophora and Bamboo Pod, Sardine, Horseface, Porgy, Chinese herring and mackerel, which are in good condition and not in overfishing condition. The other five groups, especially the eels and groupers, are overfished.
